Does superconductive shell shield gravitation?

Question

If electron is released at the center of superconductive
shperical shell what will be its acceleration?

Answer 1

These are two different questions. Superconductivity has not been shown to shield objects from gravitation, and relativity would negate the possibility.

I'm not sure how you could release an electron without breaching the superconducting shell, which would seriously affect the outcome. Simply as a "thought experiment," if you made an electron appear in the center of a superconducting sphere, it should be repelled by the shell's electrons, so it would remain in the center. If the shell was large enough (hypothetically) to not repel the electron on appearance, it would probably "bounce" from one repulsive point in the sphere to another.
